The extracts of the plant may inhibit tumor cells

There are more than 350000 kinds of seed plants in the world, which can be divided into five categories, namely, Gnetum, cycads, conifers, Ginkgo biloba and flowering plants Among them, where is the life tree of the seed plant, the origin and evolutionary adaptation of the plants are known as the "Centennial problem" in botany The reporter learned from the Municipal Urban Management Bureau yesterday that, after years of efforts, Xianhu botanical garden has led the international scientific research team to make a major breakthrough in this field and completed the world's first high-quality genetic map of gymnosperm genome The research results were published in nature plants on January 30 this year According to the relevant person in charge of the Municipal Urban Management Bureau, there are only about 40 species in 1 genus in the world, but they play an extremely critical and important role in understanding the evolution of seed plants With the support of Shenzhen Municipal Commission of science and technology, Shenzhen Municipal Bureau of urban management and China Africa Joint Research Center of Chinese Academy of Sciences, the "mamatu genome project" was launched in 2013 Based on the research foundation of Xianhu botanical garden, it has cooperated with various cooperative units to tackle problems After many years of research, we have completed the high-quality genome mapping of gymnosperms for the first time, which provides important and key data resources for the study of early seed plant evolution Secondly, the unique genomic characteristics of the plant were revealed from different levels, such as repeat sequence, intron, WGD, gene functional area distribution, which were significantly different from other reported seed plants, and the third type of repeat sequence evolution model of seed plants was found At the same time, through the comparative analysis of genomics, the project team revealed the evolutionary history of different branches of early seed plants and deduced the ancient genome characteristics of their common recent ancestors In addition, according to the relevant person in charge of Xianhu botanical garden, the project has a high application value It is found that the extracts of this family of plants have a potential specific inhibitory effect on some human tumor cells Through the project of "the project of the project of the project of the genome of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the plant of the Long, development, reproduction, genetic variation, resistance, interaction with environment and genetic improvement provide important reference and guidance information, so as to seize the commanding point of development and utilization of genetic resources and lay a solid foundation for downstream industry application.
